Specifications
Max power consumption (W): 1.5
Optical Connector: N/A
Cable type: Direct-attach copper cable assembly
The Cisco 400G QDD-400-CUxM module primarily enables high-bandwidth 400G links and supports 400G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. QDD-400-CuxM cables are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks. Cisco currently offers passive copper cables in lengths of x=1, 2, 2.5, and 3 meters.
